Een officier moet de aanvallen van een mysterieuze huurmoordenaar verijdelen. De voormalige onderzeeboot commandant Do-yeong krijgt een anonieme chantage oproep: overal in de stad zijn explosieven verborgen, waarvan de ontstekers reageren op geluid. Do-yeong haast zich van de ene plaats naar de andere om ze onschadelijk te maken. Maar de bommen legger is altijd een stap voor.
Nee, helaas is 데시벨 nog niet beschikbaar op Netflix in Nederland.
